similar to: Xen DomU supoprt in RHEL 7 and the CentOS Plan

I''ve attached a python script that collects stats from DomUs (HVM and PVM). I hope this would be useful for somebody else.

Hello all, I have a CentOS Dom0 booting CentOS DomU, I am able to start multiple DomUs from the command line using xm create, but if I copy the configuration files to /etc/xen/auto only one of the DomUs seem to start up automatically. Has anyone experienced anything similar before? Any pointers / hints? Thanks. -- "I never look back darling, it distracts from the now", Edna Mode

Hi, I'm wondering about the impact of using both dom0 and domU's on a server at the same time. I'm worried about the performance impact of running a Mysql server in a domU and now I'm thinking about moving the Mysql part of a LAMP setup into dom0 and running a few Apache guests as domUs. Since the Apaches will serve mostly from an NFS share they won't have much impact on

I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

I added a virtual interface eth0:1 on one of my machines and suddenly networking breaks on startup of the system (eth0 is gone) when xend starts and runs the network-bridge script. This is supposed to be fixed according to: https://bugzilla.redhat.com/show_bug.cgi I checked and the network-bridge script contains this fix. It works fine on one of my PCs when eth0:1 is added, but not on this

Hi all, Wondering if anyone knows of any tools I can run on my Dom0 to log various stats (like CPU usage, memory usage, etc) for each guest domain for analysis over a period of time? I can see that xentop displays that information anyway but would be nice to be able to present that information on a web based interface for day to day administration. Also any tools that send out email

I realize this might be one of those religious topics, but is there any good rule of thumb as to how to setup storage for a Xen domU? Without really knowing any better, I''m basically going to make a disk image of the OS and the create a ''data'' partition on my raid 5 volume for each virtual machine. This is for use at home, so in reality it probably doesn''t

Hello CentOS Xen experts, I am attempting my first Xen installation. I have a Centos 5.2 server (dom0) and am attempting to install a Centos 5.2 guest (domU). The install goes fine with one exception. At the end it complains "error mounting /boot". My efforts googling around the net to dig up a solution have come up empty, although I've seen similar issues reported.

Hi, how can i make actual xen kernel to work under my domU virtual machines? When i will provide as kernel /boot/vmlinuz-2.6.18-53.1.14.el5xen as ramdisk /boot/initrd-2.6.18-53.1.14.el5xen.img , it will not work becouse of error that root device does not exists. And when it is booting it is showing that raid md0 and my logical volumes does not exists - like those on dom0. I believe it is becouse

Hello, i have CentOS on xen as domU, i have installed "yum groupinstall Gnome Desktop ... " . I want to access Gnome Desktoup through XDMCP protocol, but unfortunately X server will not start when there is no graphical output where to start. How can i solve this problem? And of course i have edited gdm.conf and added to [XDMCP] Enable = True. Thanks in advance! David --------------

I am currently running Centos 5.2 with 2.6.18-92.1.13.el5xen with 2 domu's One another Centos 5.2 and another Windows XP. The Centos DomU works fine and I never have any problems however my XP DomU crashes every so often with the bluescreen DRIVER_IRQL_NOT_LESS_OR_EQUAL then under the technical information tcpip.sys addres xxxxxx base at xxxxx datetime Xxxxxxxxx Is there a driver

Hello, What is the best way to get the xen enabled CentOS 5.2 vmlinuz and initrd images for use as a guest domain (domU) on Ubuntu host domain (dom0). Is there a site where these are available? I am hoping that I could use the vmlinuz from the latest kernel rpm, if I go that route, how could I generate the initrd image given that my host is Ubuntu? These are for use with post install of domU,

I recently upgraded storage on our (first) xen server and would like to migrate the file-based vms I have in play to lvm-based storage... Can anyone point me in the right direction? Is there a way to mount a vm image file like I would using a iso image and a loopback device? Each vm''s disk file contains a partition table with root and swap partitions... In retrospect I wish I''d

Greetings CentOS Team- Since the list tends to be filled with "things don't work" and "why did you do it this way" and "complaint X", I thought I'd make a small deviation... I have a production system running on a Dell Poweredge 2650 server. I simply ran 'yum update' and rebooted with no problems. Everything continues to work as rock solid as before.

Is there any reason why I would not want to set dom0-min-mem to 0 or to what I set dom0_mem on my kernel line? Setting to 0 or setting to the same value as dom0_mem disables memory balloon correct? I cant seem to think of a reason why I would want memory ballooning. Also setting dom0-min-mem should that be done in xend-config.sxp or on the kernel command line? -- Nick Anderson

I had an issue late yesterday where some windows domU''s were down. The person who "owns" those domUs let windows updates install and then restart, which they failed to restart. When I tried to manually restart them I was getting can''t allocate memory errors. In the past I''ve had can''t allocate memory errors when trying to bring up a new domU.

Hi all, I am running Scientific Linux 5.1 (rhel 5.1 compatible) 64bit on a 2x4core system with 16 gb ram with 3 Scientific Linux 4.6 (rhel 4.6 compatible) guests an one Scientific Linux 5.1 guest. I do not run ntp on the guests but only on dom0. One specific Scientific Linux 4 domU always looses time synchronization with dom0. All the others SL4 and the SL5 domUs remain synchronized. There
